Concerns have increased over the security of personal information collected by the Department of Health and Human Services (HHS) as the volume of personal data has multiplied dramatically with the implementation of Obamacare. Security experts have testified before Congress about flaws they have uncovered at Healthcare.gov, and various press reports have related other potential problems with the website or with information flowing to the Federal Services Data Hub that could be exploited by hackers and identify thieves. An HHS document dated December 5 describing a more than 500 percent increase in the monitoring of cyber threat indicators since April 2013 may only increase those concerns.
